I think that’s for strength as well as brake. There was a brand with the name beginning with M Magura? No idk what it was. I have the suntour rox shox knockoff and it’s been great it’s a threadless but it’s not a triple tree.
I’ve seen some stiff tripple trees with the clip ons. Haven’t seen any with suspension and tripple trees. The suntour is pretty good I have a 180mm disc on mine. Maybe one from a dirt bike could work. I’m sure someone makes a clip on adapter for the single tube front suspension. I’d say it helps when I hit the same pothole all the time going up the road lol. This is my bike, it’s a beach cruiser with front suspension and mountain bike handlebars.
No, I'm just looking to build a strong bike that's nice to ride. I might not go with clip-ons, they're not very comfortable. My last bike was a old raleigh road bike with 27 x 1.25 tires on it, rigid, rim brakes all around. I was thinking of doing a build with the in-frame gas tank frame.
